There are tougher tests to come
The England team can definitely take encouragement and confidence from Monday's win. There will, however, be more stern tests to come, in both the group stage and the knock-out rounds, should England make it past the opening round. Tunisia are by no means minnows, as their world ranking of 21 puts them higher than any other African team.
They are not, however, comparable to the Belgian national side, which boasts a vast array of talent and some of the world's best players. England will have to cope with the likes of Romelu Lukaku, Eden Hazard, Kevin de Bruyne and Dries Mertens; by no means an easy task.
For large parts of the game, England could find themselves on the back-foot needing to defend with their backs against the wall. England's ability to create one last opening and clinch the win against Tunisia was a demonstration of resilience and steel; two things they will need against the Belgians and any future opponents.
